| Abstract: | Hybridization of porous synthetic polymer and sophisticated ligands play an important role in transition-metal catalysis for chemical transformations at laboratory and industrial levels. A monolithic porous polymer, which is a single piece with continuous macropores, is desired for high permeability, fast mass transfer properties, high stability, and easy modification. Herein, we first develop a monolithic porous polystyrene containing three-fold cross-linked PPh3(M-PS-TPP) for transition-metal catalysis. The monolithic and macroporous structure ofM-PS-TPPwas fabricated via polymerization-induced phase separation using porogenic solvent. Moreover, theM-PS-TPPwas synthesized using different feed ratios of divinylbenzene (DVB) for site-isolation and mono-P-ligating behavior of PPh3.P-31 CP/MAS NMR analysis revealed that the different selectivity ofM-PS-TPPs was obtained in formation of mono-P-ligation toward Pd-II. The macroporous properties and controlled mono-P-ligating behavior ofM-PS-TPPfacilitated the challenging Pd-catalyzed Suzuki-Miyaura cross-coupling reaction of chloroarenes. |
